31 August - 5 September 2025, 10th International Workshop on Artificial Intelligence and Theorem Proving (AITP 2025), Aussois, France

Date: 31 August - 5 September 2025
Location: Aussois, France
Deadline: Monday 5 May 2025

Large-scale semantic processing and strong computer assistance of mathematics and science is our inevitable future. New combinations of AI and reasoning methods and tools deployed over large mathematical and scientific corpora will be instrumental to this task.  The AITP conference is the forum for discussing how to get there as soon as possible, and the force driving the progress towards that.

There will be several focused sessions on AI for ATP, ITP, mathematics, relations to general AI (AGI), Formal Abstracts, linguistic processing of mathematics/science, modern AI and big-data methods, and several sessions with contributed talks. The focused sessions will be based on invited talks and discussion oriented. AITP'25 is planned as an in-person conference.

16 September 2025, 11th Workshop on Formal and Cognitive Reasoning (FCR 2025), Potsdam, Germany

Date: Tuesday 16 September 2025
Location: Potsdam, Germany
Deadline: Friday 4 July 2025

In real-life AI applications, information is usually pervaded by uncertainty and subject to change, and thus requires non-classical systems. At the same time, psychological findings indicate that human reasoning cannot be completely described by classical logical systems. Sources of explanations are incomplete knowledge, incorrect beliefs, or inconsistencies. A wide range of reasoning mechanisms, such as analogical or defeasible reasoning, have to be considered, possibly in combination with machine learning methods. The field of knowledge representation and reasoning offers a rich palette of methods for uncertain reasoning, both to describe human reasoning and to model AI approaches.

This series of workshops aims to address recent challenges and to present novel approaches to uncertain reasoning and belief change in their broad senses, and in particular, provide a forum for research work linking different paradigms of reasoning. A special focus is on papers that provide a base for connecting formal-logical models of knowledge representation and cognitive models of reasoning and learning, addressing formal and experimental or heuristic issues. FCR'25 will be co-located with the 48th German Conference on Artificial Intelligence (KI 2025).

Date: 24 - 26 September 2025
Location: Kyoto, Japan
Deadline: Monday 9 June 2025

 The conference is concerned with the theory of computability and complexity over real-valued data. Scientists working in the area of computation on real-valued data come from different fields, such as theoretical computer science, domain theory, logic, constructive mathematics, computer arithmetic, numerical mathematics and all branches of analysis. The conference provides a unique opportunity for people from such diverse areas to meet, present work in progress and exchange ideas and knowledge.

The topics of interest include foundational work on various models and approaches for describing computability and complexity over the real numbers. They also include complexity-theoretic investigations, both foundational and with respect to concrete problems, and new implementations of exact real arithmetic, as well as further developments of already existing software packages. We hope to gain new insights into computability-theoretic aspects of various computational questions from physics and from other fields involving computations over the real numbers.

Invited Speakers: Takako Nemoto (Sendai, Japan), Selwyn Ng (NTU, Singapore), Yudai Suzuki (Oyama, Japan) and Patrick Uftring (München, Germany).

23 - 26 September 2025, The 18th European Conference on Symbolic and Quantitative Approaches to Reasoning with Uncertainty (ECSQARU'25), Hagen, Germany

Date: 23 - 26 September 2025
Location: Hagen, Germany
Deadline: Thursday 8 May 2025

The biennial ECSQARU conferences constitute a major forum for advances in the theory and practice of reasoning under uncertainty, with a focus on bringing symbolic and quantitative aspects together. Contributions come from researchers interested in advancing the scientific knowledge and from practitioners using uncertainty techniques in real-world applications. The scope of the ECSQARU conferences encompasses fundamental issues, representation, inference, learning, and decision making in qualitative and numeric uncertainty paradigms.

The following keynote speakers are already confirmed: Claudia d'Amato (University of Bari, Italy), Vanina Martinez (Artificial Intelligence Research Institute, Spain) and Tommie Meyer (CAIR, University of Cape Town, Source Africa). The first day (Sep 23) is dedicated to a workshop and tutorial programme. A separate call for workshops and tutorials has already been disseminated (see the website for details). A Best Paper Award supported by Springer will be granted at the conference.

23 - 26 September 2025, 5th European Conference on Argumentation (ECA 2025): Argumentation in the Digital Society, Warsaw, Poland

Date: 23 - 26 September 2025
Location: Warsaw, Poland
Deadline: Saturday 1 March 2025

The European Conference on Argumentation (ECA) is a biennial pan-European initiative aiming to consolidate and advance research on argumentation. After four successful editions, ECA will be hosted in 2025 by the Warsaw University of Technology, in Warsaw, Poland. We aim to attract scholars on argumentation worldwide from various disciplines, dealing with a range of themes and adopting a variety of approaches.

The special theme of this conference is Argumentation in the Digital Society. The main objective of the conference is to identify the key research areas related to the dynamics of change and development in today's digitised society. There is a need to develop the theoretical tools of argumentation and related disciplines that allow discussion and argument to be founded on trust, charity, and goodwill. The conference aims to explore these topics and ensure a high-quality exchange of research results.

The ECA 2025 summer school organized by Barbara Konat and Leonard Kupś (Faculty of Psychology and Cognitive Sciences) will take place at Adam Mickiewicz University, in Poznań, Poland, before the ECA conference, from 17th to 20th September 2025. The summer school allows Early Career Researchers to explore current methods in the empirical analysis of natural language argumentation. This includes a variety of topics such as formal and informal logic, erotetic logic, computational approaches, conversation and discourse analysis, and experimental methods in psychology with a strong focus on practical, hands-on analysis.

24 - 26 September 2025, 22nd International Conference on Computability and Complexity in Analysis (CCA 2025), Kyoto, Japan

Date: 24 - 26 September 2025
Location: Kyoto, Japan
Deadline: Monday 9 June 2025

 The conference is concerned with the theory of computability and complexity over real-valued data. Scientists working in the area of computation on real-valued data come from different fields, such as theoretical computer science, domain theory, logic, constructive mathematics, computer arithmetic, numerical mathematics and all branches of analysis. The conference provides a unique opportunity for people from such diverse areas to meet, present work in progress and exchange ideas and knowledge.

The topics of interest include foundational work on various models and approaches for describing computability and complexity over the real numbers. They also include complexity-theoretic investigations, both foundational and with respect to concrete problems, and new implementations of exact real arithmetic, as well as further developments of already existing software packages. We hope to gain new insights into computability-theoretic aspects of various computational questions from physics and from other fields involving computations over the real numbers.

Invited Speakers: Takako Nemoto (Sendai, Japan), Selwyn Ng (NTU, Singapore), Yudai Suzuki (Oyama, Japan) and Patrick Uftring (München, Germany).
